Abstract
System and method for delivery monitoring and occlusion detection in an infusion pump The present disclosure provides systems and methods for delivery monitoring and occlusion detection in an infusion pump and uses thereof. The systems of the present invention are fast and can be modular. The systems and methods allow for direct, accurate, precise, sensitive, and non-invasive measurement of the force required to displace a plunger in an infusion pump.
Claims24
A system for delivery monitoring and occlusion detection in infusion pump, comprising:
- at least one force transmission member (1) comprising at least two ends;
- at least one plunger (2) or piston;
- at least one force sensor (3);
- wherein at least one end of said force transmission member (1) is facing said plunger (2) or piston and at least one end is facing said force sensor (3);
- wherein said force sensor (3) is placed close to or in immediate contact with the force transmission member.
A modular force sensing unit capable of retrofitting in an infusion pump for allowing delivery monitoring and occlusion detection, comprising:
- at least one force transmission member (1) comprising at least two ends;
- at least one force sensor (3);
- and
- at least one mounting member (8) configured to allow retrofitting of the modular system in an infusion pump;
- wherein at least one end of said force transmission member (1) is facing plunger (2) or piston of said infusion pump and at least one end is facing said force sensor (3);
- wherein said force sensor (3) is placed close to or in immediate contact with the force transmission member (1).
A method for delivery monitoring and occlusion detection in an infusion pump comprising:
- i) pushing at least one plunger or piston by at least one force transmission member further in syringe barrel of the infusion pump during each actuation;
- ii) transmitting force from the plunger or piston to at least one force sensor by the force transmission member during each actuation;
- iii) capturing force required by force transmission member during every additional actuation;
- iv) analyzing captured force data and comparing it with pre-set threshold, patterns of force to detect occlusion or any anomaly in normal delivery.
A method for contact detection between force transmission member and plunger or piston in an infusion pump during priming comprises one or more of the following steps:
- a) initializing system and starting priming sequence followed optionally by calibrating at least one force sensor;
- b) beginning movement of at least one force transmission member towards at least one plunger or piston;
- c) monitoring data of at least one force sensor;
- d) analyzing data of at least one force sensor to detect contact;
- and
- e) determining plunger position based on piston movement.
A method for monitoring reservoir seating in an infusion pump comprising one or more of the following steps:
- a) Starting priming sequence followed by movement of at least one force transmission member towards at least one plunger or piston to initiate contact;
- b) Monitoring data of at least one force sensor;
- c) Recoding force value at point of contact of the piston and the plunger;
- and
- d) Analyzing force data for patterns indicative of reservoir seating correctness.
A method for distinguishing between normal and occluded delivery in an infusion pump comprising one or more of the following steps:
- i) initializing system for delivery;
- ii) actuating at least one piston;
- iii) monitoring and analyzing force data;
- and
- iv) Identifying and responding to potential occlusion based on force data deviations.
